World’s Biggest Submarine Pipeline Plough To Be Built In Baltic Sea

The world’s biggest submarine pipeline plough, PL3, arrived in the Baltic Sea on the floor of mother ship Far Samson. The subsea plough will be used to embed the Nord Stream Pipeline in Swedish and Danish waters.

Lowering of the pipeline below seabed level using PL3 ensures that the pipeline will stay stable in its position throughout its lifetime. Ploughing of the first pipeline is scheduled to be performed at many locations along the pipeline route between early February and mid-March, 2011.

Model simulations have shown that ploughing will have no important impact on flora and fauna as sediments will settle quickly. As part of its environmental monitoring program, Nord Stream will monitor the water quality before, during and after trenching to verify that the results of the model simulation are correct and that Nord Stream is fulfilling permit requirements.
